The problem here is that the icons get installed to /usr/share/notify_osd as opposed to /usr/share/notify-osd. A change was recently committed to change the PACKAGE_NAME from notify_osd to notify-osd, by modifying the name passed to AC_INIT in configure.in. However, PACKAGE_NAME in the actual configure script used to build the package still says notify_osd, which is why the icons get installed in the wrong place. So the configure script used to build the package was generated from the old configure.in file (when the package name was notify_osd).
Bug 331383 is "fixed".
